Application filed August 2,

To all whom it may concern.-

Be it known that I, WiLLLiii F. Zrnnarn,

Sheboygan, in the county of Sheboygan and State of Wisconsin, haveinvented a new and useful Improvement in Developing, Washing, and FixingBoxes, of which the following is a specification.

This invention relates to photographic film, developing, fixing andwashing tanks, the object being to provide a tank so constructed thatthe films can be placed. therein and developed fixed and.vashed'withoiit handling the same.

Another obj ectof my invention is to pro- 'vide a tank which will beperfeetiy light tight and yet be provided with inlet and outletopenings, so that the developing fixing and washing liquid can readilypass therethrough without admitting any light.

With these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts,hereinafter fully described and pointed out in the claims.

In. the drawings forming a part of this specification:-Figure 1 is aperspective VlBW of my improved tank showing the cover raised. Fig. 2 isa top lan view of the tank with the cover remover. Fig. 3 is a sectionalview taken on lines 33 of Fig. 2. Fig. 4 is a sectional view taken onlines 44 of Fig. 2. Fig. 5 is a sectional view taken on lines 55 of Fig.2. Fig. 6 is a sectional view taken on lines 66 of Fig. 2. Fig. 7 is asectional view through my im roved film holder. Fig. 8 is a detail viewof a modified form of a partition showing a roller-arranged on the end.

Referring to the drawings A indicates a rectangular metallic tank havingindentations and projections formed in its sides A, A Spaced partitionsB, B extend inand pro'ections formed in their sides, and provide withenlarged rounded ends 13.

The indentations and projections in the partitions hold the film awayfrom the partitions so, as to allow the liquid to circulate between thesame. Projecting inwardly from the end A are spaced partitions C, Cwhich are also rovided with indentations and projections Specificationof Letters Patent.

sides so that the liquid will have to pass around the ends of the same.

The partition B is connected to the side A by a partition D, forming areceptacle N and the partition is provided with parallel rows ofperforations D, through which the liquid is adapted to pass into thetank.

A partition E connects the partition 0 to the side A of the tank forminga receptacle 0 and the partition is provided with arallel rows ofperforations E, through which the liquid passes into the receptacle.'The partition and end of the tank in the receptacle is.

provided with projections E so as to prevent any light from passing intothe tank through the outlet openings E "formed in the end of the tankleading into the receptacle.

A flanged top F is adapted to fit over the tank and completely closesthe same, so that it will be, perfectly light tight. An opening F isformed in the flange of the cover, in alinement with the opening E inthe receptacle, and the top of the tank.

is provided with a downwardly rojecting spout G fitting into the link D.he opposite sides of the spout being provided with inwardly projectingpartitions G so as to prevent light from passing down into the tank. Theneck of a funnel H is adapted to be inserted in the spout G, so that theliquid can be readily poured into the tank.

A stud pin I projects out from the bot- I tom of the tank adjacent thereceptaclefE, on which is mounted the socket end of a rod I, over whichis placed the curled end of the film to be developed, the other endbeing drawn around through the tank over the ends of the partitions, andsecured in a clamping member J, secured to the partition D. The clampingmember comprises a split tube J between the ends of which is arranged apair of clamping members J between which the end of the film is clamped.A pair of sockets J are secured on the outside of the tube adapted toiit over a pair of spaced pins K, secured to the partition D between therows of perforations so that the liquid will enter the tank to each sideof the film and pass around the partitions and out through the openingin the receptacle:

In the modification shown in Fig. 8, I have shown a partition L, inwhich is mountin their sides and enlarged ends C which divides the tankinto opened compartments. t The partitions are ot the same height as thetending inwardly from its ends,
